Claims (7)

  1. Support pour un ou plusieurs éléments porteurs de charge (1) de préférence semblables à des plaques, pour l'utilisation dans un four de traitement, de préférence une presse isostatique à chaud, comportant un élément de support pratiquement cylindrique (2, 3) qui repose sur un support sous-jacent (4), se présentant de préférence sous la forme d'une plaque inférieure, et un isolant thermique (10) disposé dans cet élément de support (2, 3), caractérisé en ce qu'une partie au moins de l'élément de support cylindrique est réalisée sous la forme d'un certain nombre de segments (3) s'étendant axialement, disposés côte à côte le long de la périphérie de l'élément de support, en ce que ces segments (3) sont prévus pour être accouplés à des éléments adjacents (2, 4) aux parties supérieure et inférieure, au moyen d'un accouplement qui est conçu pour guider le segment dans un mouvement semblable à celui d'une charnière par rapport aux éléments adjacents (2, 4), afin d'absorber les mouvements radiaux qui se produisent dans les segments (3) sous l'effet de la différence de température entre les parties supérieure et inférieure de l'élément de support.
  2. Support selon la revendication 1, caractérisé en ce que la hauteur de l'isolant thermique (10) correspond au plus à la hauteur des segments axiaux.
  3. Support selon la revendication 1 ou 2, caractérisé en ce que l'élément de support cylindrique est conçu de façon à comprendre également, en plus des segments axiaux (3), une virole supérieure (2) disposée au-dessus des segments, dans une configuration dans laquelle l'élément porteur de charge (1) repose sur cette virole supérieure.
  4. Support selon la revendication 3, caractérisé en ce que des chevilles (7) sont disposées à la surface de contact entre les segments axiaux (3) et la virole supérieure (2), ces chevilles étant disposées dans des cavités qui sont formées respectivement dans les segments et dans la virole supérieure.
  5. Support selon l'une quelconque des revendications précédentes, caractérisé en ce qu'à la surface de contact entre l'élément porteur de charge (1) ou la virole supérieure (2) et des segments axiaux (3), et/ou entre les segments et le support sous-jacent (4), des saillies sont formées dans les segments, l'élément porteur de charge, la virole supérieure ou le support sous-jacent, ces saillies pénétrant dans des cavités correspondantes dans les éléments en regard, ou en ce que des cavités en regard sont formées dans les deux éléments, et une pièce intermédiaire pénètre dans les deux cavités, pour guider les éléments dans un mouvement mutuel semblable à celui d'une charnière, en relation avec les mouvements radiaux qui se produisent sous l'effet de changements de température.
  6. Support selon l'une quelconque des revendications précédentes, caractérisé en ce que les segments axiaux (3) sont fixés à un anneau déformable (6) au moyen de vis (13) qui sont disposées dans la partie inférieure ou supérieure des segments.
  7. Support selon l'une quelconque des revendications précédentes, caractérisé en ce que l'élément de support cylindrique est partiellement perméable aux gaz.
